Radioactive gas has been found in the soil of a housing development in Wells, Somerset Live can confirm.

David Wilson Homes, which is developing Bishops Green on Wookey Hole Road has said that soil in the area has been sampled and tested positive for radon gas.

Built on the site of a former Thales radar factory, the housing developer insists that "no undue levels of radon have been found".

However, Somerset Live understands that the company has delayed completion on some of the contracts for homes in the development.

Radon, which is colourless, odourless and tasteless gas produces radioactive dust in the air and can increase the risk of lung cancer.

Ian Menham managing director of the housing company: "We have a rigorous and detailed screening programme at the development in Wells with ongoing testing of soil as required by the NHBC and Mendip District Council.

"Soil across the site has been sampled and we regularly retest soil to monitor quality. No undue levels of radon have been found and work continues on site.
